Two 303 products provide UV protection. Which one should be used on sailcloth?
303 Fabric Guard is for textiles…fabrics, carpeting…synthetic and natural materials that are inherently absorbent. Generally speaking, synthetic textiles are various types of plastics, but plastics that are made to mimic the appearance, texture and absorbency of natural fibers. 303 Protectant is for plastics, synthetic materials in an inherently repellent form. Many plastics can be manufactured in both forms. One example is polyester. Polyester carpeting is polyester resin in a textile form….spill water or other liquid on it and it absorbs like cotton. Or in another form, polyester resin is the gelcoat fiberglass in your boat, jet ski or snowmobile, nothing at all like a textile, but hard & repellent to water. Acrylics, nylons, polypropylene and many other plastics in both forms are common components of innumerable consumer items. So whether 303 Protectant or 303 Fabric Guard may be used depends primarily not on the type of plastic, but the form into which the plastic is made. Sa
